【问题描述】:
我需要从相机捕获图像并将其存储到 imageView。
Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePicture, 0);
和onActivityResult方法:
Uri selectedImage = imageReturnedIntent.getData();
mPhoto.setImageURI(selectedImage);

【解决方案1】:
就这样试试吧:
此代码用于从相机捕获图像并显示在 imageview 中。
public class MainActivity extends ActionBarActivity {
ImageView imgFavorite;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void imageClick(View view){
imgFavorite =(ImageView)findViewById(R.id.imageView1);
open();
}
public void open(){
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); //IMAGE CAPTURE CODE
startActivityForResult(intent, 0);
}
protected void onActivityResult(int requestCode,int resultCode,Intent data){
super.onActivityResult(requestCode,resultCode,data);
Bitmap bitmap=(Bitmap)data.getExtras().get("data");
imgFavorite.setImageBitmap(bitmap);
}
}
xml 文件:
<ImageView
android:id="@+id/imageView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="14dp"
android:layout_marginTop="16dp"
android:contentDescription="@string/hello_world"
android:onClick="imageClick"
android:src="@drawable/camera_launcher" />
